<p>The present invention provides a surface-covered inorganic powder having novel physical properties. The surface-covered inorganic powder is an inorganic powder covered with a monolayer formed by at least one structural unit represented by formula (I):
(wherein R 1 represents an alkyl group having 1 to 30 carbon atoms and optionally having a substituent, X 1 and X 2 each independently represent a hydroxyl group, or an OR 2 or O-Si bond, and €¢ represents a binding site to an atom on the inorganic powder side),
wherein the monolayer is at least partially crystalline. The surface-covered inorganic powder is produced by, for example, bringing an inorganic powder into contact with a solution for forming an organic thin film containing (A) at least one compound represented by formula (II) (wherein R 1 represents an alkyl group having 1 to 30 carbon atoms and optionally having a substituent, X 3 represents a hydrolyzable group, and n represents any integer of 1 to 3), (B) water of 10 ppm to a saturating concentration, and (C) an organic solvent.</p> |
